Adaptor seal



FIG. 1 is a front perspective view of an adaptor seal according to our design; and,

FIG. 2 is a left side view thereof, with the right side view thereof being a mirror image thereof.

The top and bottom views are not shown because they are similar to FIG. 2, the only difference is that the top and bottom views would be rotated 90° clockwise and 90° counterclockwise, respectively, compared to FIG. 2.

The broken line showing of a portion of the seal is included for the purpose of illustrating environment and forms no part of the claimed design.

The dotted lines represent the border between claimed and unclaimed subject matter and do not form part of the claimed adaptor seal design. 

The ornamental design for an adaptor seal, as shown and described.
